Otago Engineering (previously IRONGEAR by A.J Grant) spiral staircases are custom designed and manufactured in Dunedin, creating a stylish look as well as a space-saving choice for home or office building.

Recently Otago Engineering was commissioned to build four spiral staircases to fit into apartments in Auckland where space was of the essence and only spiral staircases would do.Otago Engineeringspiral staircases are designed to be space-saving and take up little more floor space than their diameter.

Our designer followed the building plans meticulously and designed the spiral staircases to suit the space allowed for in the apartments. The spiral staircases were then manufactured and assembled in one piece in our workshop in Dunedin. They were then closely monitored and checked to make ensure they were built to the highest standard before shipping to their destination in Auckland.

On arrival, they were transported to the site and craned into position with a minimum of fuss making this cost-efficient solution for space-saving stairs.

Testimonial

When we looked for manufacturers of good quality spiral staircases for our premium townhouse development in Auckland, we had a real struggle to find someone to manufacture these and even looked at manufacturers in Australia. In the end, due to the obvious knowledge that can only come from years of experience and excellent service that Allan from Grant Engineering in Dunedin provided, we chose them to manufacture 4 of these complicated staircases. The end product was superb and their help in recommending appropriate coatings for coastal installation, as well as help in transporting these to Auckland, was simply outstanding. To the entire team at Grant Engineering - you rock!
